vfoiaims.` (cizafio'n Myinventionrelates to a scraper mechanismIparticularly foruse in connection with cooking i Y yreceptacles Vused inthe"-manufacture of candy or similarproducts, where it is necessary tokeep Avthe materialbeing cooked from adhering to the sides of the VesselWhile the cooking operation is taking place. j Y A further object of 4myinvention is the provision of a scraper mechanism for use particularlyirl-vessels or kettles composed of copper and in which the kettles arefashioned by being lhammered into properv Shapathereby leaving theprints of the hammer Vmarks on the surface of thekettle making'thesurface slightly irregular so that the scraper "must `conform to theirregularities of the metal in order to remove the material from thesides of the kettle.

"Another and further object is the provision of a scraper which ispreferably made from wood and fashioned in v`such manner that the endsof thegscraper will `conform to the irregularities of the kettle andwhich,`being comparatively soft,

will not injure or scratch `the surface of the kettle, such as mighthappen if metal wereused, particularly withI a copper kettle which is asoft materiaL l Another and further object of the invention is j theprovision of a scraper which is under tension whenplaced in ythe kettlein such manner that,v

itt-exerts a constant pressure on the sides ofthe kettle so as toremoveallmaterial therefrom during `the ,cooking operation,4 and whichpolishes` theprogvision of scraper mechanism in which the` j tension orpressure on the Scrapers can be `adf justedso as to be kept uniformandlwhich retains the operating shaft in proper* alignment andthe Wholeiscraper operating:4 mechanism thereby kept in balanced relation.A

I am aware that it is common practice,par ticularly in thecandy makingart, to use kettles .with Scrapers, but thesescrapers have provenunsatisfactory in service and cannot be `held in frictional engagementwith the sides of the ket- Ofall the material which is being cooked fromthe sides of the kettle, andwhich at the same t time will conform to theirregularities in the sur--A faceofl'the kettle. Inpractice I have foundthat the use of the scraper of my invention reduces tlewith suflicientpressure toinsure the removal the time vof cookingnthe candyapproximately one-third and thereby shortens `the time oft-the cookingoperation very materially, increasingthe capacity of the kettles andalso lessening .the

vchances of the batch4 being:` cooked `becoming dark, whichl happenswhen thematerials` used inmaking up the, candy are cooked for a longer:period of time. In other words, `the longerthe material is cooked thedarker it becomes during the cooking operation. l The use of my improvedscraper lessens the time necessary for thecooking operation, thus notAonly increasing the capacity of the kettlesbut increasing thequality ofthe candy cookedin the kettles as well. 1; These andv other objects ofmy inventionl will be more fully andfbetter understood; byreference tothe accompanying sheet of drawings, in Whichl l i i Figure 1 is aVertical sectional -view of a candy kettle embodying my invention; jFigure 2 is a top plan view of the kettle having my invention embodiedtherein; t Figure 3 is a'detailed `sectional iviewtshowing, one of thescrapers'in position on thesideof the kettle;lf w yFigurevl is aperspectiveview of one of the individual scraping members; Aand p y j iFigure 5 is a modified form of scraper whichl may be employed instead ofthe form illustrated the othergures.` p Y A l Referring now specificallyto the drawing, akettle Il! illustrated, commonly made A of `cop-v per,with a jacket l lextending therearound with a plurality'of supportinglegs l2, l-2 being provided.` A steam `pipe I3 extends throughv thejacket i IV so as todisch-arge steam into the spaceM between the kettlel0 and the jacket-l I-, itsbeing common to cook `the material inthesevkettleskby` means `of live steam discharged against thefsure-`face of the -kettle I0. l Extending vertically in the kettle l Il is ashaft i4 which extends into a bear?-A ing l5 at the bottom of the`jacket Hfand has mounted thereon a D-shaped member l 6, the circularportionof which conformssubstantially to, the curvature'of the kettlellt and isf` spaced a short distance, therefrom as shown particularly inFigures l` and 3. Mounted Aupon the shaftl4A is a stirring paddle I lwith -a gear I8 mounted uponthe `upper end of theashaft M-for engagementwith a suitable cooperating gear on a shaftv I8a'leading to any sourceof power adapted to drive the mechanism when in operation. The shaftI8*L l may be .appropriately journaled order tohold the D-shaped memberin the kettle,

althoughvusually the D-shaped member Withthe` H shafts is` suflicientlyheavy so the Scrapers are.` held inpropericontact with the surface ofthekettle. *i I y `Secured around the inner periphery-of the D shapedmember is a pluralityy lof, `paddles or lzUNqiTo s'rATEs PATENT OFFICErScrapersI9,'-'l 9, one of these Scrapers being shown in detailinFigurel.
